I don't know how they do things in Barcelona, but in the US the rainwater has its own sewer system. If it didn't the waste water treatment plants would be overrun every time it rains.

Combined sewers are common in the US. https://en.m.wikipedia.org/wiki/Combined_sewer https://en.m.wikipedia.org/wiki/Combined_sewer

  My understanding is that combined sewers are being phased out whenever possible for the reason I gave.

    I'm not sure how much you know about Barcelona but it's an ancient city who's history can be traced back through to the Neolithic period with very narrow streets designed before motor vehicles. It's not really compatible to any US city.

    They have exactly that problem, but it didn't stop dozens of American cities being built with them.

In my original comment: > Per the study, sewage includes rainwater from open drains. There are even more details in the study.
